Our unique Expert Ratings combine scores from 25 of the top UK motoring websites

Mercedes-Benz GLB

(2019 – present)

The Mercedes-Benz GLB is a mid-sized SUV available with either five or seven seats. It is based on the smaller GLA model, although it is closer in size to the larger GLC. The GLB arrived in the UK in late 2019.

The GLB is currently available with either a petrol or diesel engine, although a plug-in hybrid is likely to join the range at a later date. There is also a high-performance model called the Mercedes-AMG GLB 35 – we are building a separate page for this model, so be sure to check back soon.

As of September 2020, the Mercedes-Benz GLB holds a rating of 77% on our unique Expert Rating index, based on 16 different UK reviews from the UK’s leading automotive websites. It has received praise from reviewers for its comfort, safety and advanced technology; however it has been criticised for limited practicality compared to similarly-priced rivals, and for only offering a limited choice of engines.

Overall rating: 5 stars
Date tested: November 2019









Eco Rating

Independent emissions and efficiency ratings from Green NCAP

No eco rating

The Mercedes-Benz GLB has not yet been lab tested by Green NCAP. This is a new initiative, launched in 2018 as a sister organisation to Euro NCAP. As yet, very few new cars have been tested for environmental impact by Green NCAP, and the testing programme was halted in early 2020 by the coronavirus pandemic. It is due to resume in the second half of the year.

Security Rating

Independent vehicle theft and security ratings from Thatcham Research

No security rating

The Mercedes-Benz GLB has not yet been tested for anti-theft protection by Thatcham Research. This is a new initiative that was launched in 2019 to assess, in particular, the security of new cars with keyless entry and keyless start systems.
